意味

Notification; announcement; notice. The formal or official act of informing someone of something important.

Widely used in medical, legal, and administrative contexts. In medicine, 病名告知 (byoumei kokuchi) refers to disclosing a diagnosis — particularly a serious or terminal one — to a patient, which has been a subject of significant ethical debate in Japan. In advertising it refers to advance publicity (kokuchi koukoku). The term implies a degree of formality and consequence not found in everyday 知らせ (shirase, notice/news).
